The combination of these two conditions is rarer still, and the hemodynamic consequences of these combined lesions have important considerations that may affect diagnosis and management. In this article, we present a series of three cases from our valve clinic diagnosed and managed using multimodality imaging and a brief literature review of this combined entity.
